In two months, I haven't seen any system that would require this
.section .note.GNU-stack,"",@progbits
annotation in the .s files.

I've seen SELinux systems, e.g. CentOS 5.8, Fedora 1, Fedora 13, PowerPC64.
None had this problem.

It looks like the problem existed between ca. 2003 and 2011 in some setups but nowadays no SELinux system requires this.

Hi
what does "doesn't seem to be necessary" mean?
did you build clisp with the non-stack-executable libffcall?
does "make check" in clisp work?
Thanks!

Hi!

libavcall and libcallback have both stacks marked executeable which has negative impact on SELinux systems and doesn't seem to be necessary.
